Application Type | Engine-Specific Replacement Part for 3512B Series |
The 386-1771 fuel injector is specifically engineered for the 3512B V12 diesel engine platform, delivering precise fuel delivery across industrial, generator, marine, and mining applications. This injector is compatible with multiple 3512B variants, including industrial, generator, power module, emergency gen, and continuous duty configurations, making it a versatile solution for the entire engine family. The 3512B is a 4-stroke, turbocharged, aftercooled engine featuring electronic unit injection, water cooling, and direct injection technology, and this injector is built to integrate seamlessly with these advanced fuel system specifications.
Manufactured from high strength alloy steel, the 386-1771 features a precision machined nozzle for uniform spray pattern, high pressure control for efficient atomization, and a hardened steel body for extended service life in demanding operating conditions. OEM dimensional accuracy ensures direct replacement without modification, while corrosion resistant coating enhances durability in marine and offshore environments. Each unit is leak and flow tested to confirm reliable performance before shipment, meeting industrial and OEM quality standards for heavy-duty reliability.
Installation requires fuel system cleanliness, injector bore inspection, new seals/O-rings, torque per service manual, and a post-install leak test, with ECM calibration recommended. Routine maintenance includes using approved diesel fuel and filters, monitoring fuel pressure and return flow, periodic flow rate testing, inspecting seal condition and injector balance, and replacement at service intervals. Authorized cross reference numbers for this part include 386-1771, 3861771, OE3861771, OEM3861771, CAT3861771, -3861771, 20R-1280, 246-1854, 392-2000, 10R1278, 20R-1265, and 20R-3477.
